Flatten hull into an array of indices about d3-delaunay

Agree. That would be cleaner! 👍

I’ve tinkered a little bit with this in the flat-hull branch. My first inclination was that the hull should be represented simply as an array of point indexes [i0, i1, …]. But this isn’t a convenient representation for rendering the Voronoi—the Voronoi needs to know the triangle that includes the edge between points i and i + 1 so it can look up the circumcenter. So I think it needs to be a flat array of triangle vertex indexes, where each triangle vertex i’s half-edge is the next vertex on the convex hull.
